FASTENING FOR RAILWAY-RA! LS.

SPECIFICATION forming part of Letters Patent No. 595,212, dated December 7, 1897.

Application filed July 15,1897. Serial No. 644,723.. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK W. Sermon- DER, engineer, a citizen of England, residing at Newman Street, Newtown, near Sydney, in the Colony of New South \Vales, but at present of 3 and a Bevis Marks, in the city of London, England, have invented a certain new and useful Improvement in Fastenings for Railway-Rails, of which the following is a specification.

\Vhen a railway-rail is secured in chairs by a wooden wedge driven between the rail and one of the jaws of the chair, this wedge, by shrinkage or the hammering action to which it is subjected, often becomes loosened and shaken out, leaving the rail loose.

My invention relates to simple and effective means of preventing escape of the wedge, as I shall describe.

Referring to the accompanying drawings, Figure 1 is a section of the rail with the chair and wedge shown in elevation. Fig. 2 is a plan of part of the rail and chair. Fig. 3 is a front view, and Fig. l is an edge'view, of part of the fixing-strip.

R indicates the rail, 0 the chair, and D the wedge, driven between the rail and the jaw E of the chair.

I prepare by rolling or otherwise a thin bar or strip F, of iron or steel, having preferably one of its sides rounded, from which side sharp studs f project at intervals. Before driving the wedge D into its place I hammer on one side of the wedge a length of the strip F, so that the strip is wholly or partly embedded in the wedge, its studs f being firmly engaged in the wood.

\Vhen the wedge D is driven tight between the rail and the jaw, I bend at right angles the end parts of the strip F, that extend beyond the sides of the jaw, so that they embrace the jaw between them. As the strip is thus prevented from moving in the direction of its length, the wedge which is held to the strip by the studs f cannot move lengthwise.

lVhen there is occasion to drive the wedge farther, the ends of the strip are unbent, and when the wedge is farther driven they are bent again at the fresh places, determined by its change of position.

Having thus described the nature of this invention and the best means I know of carrying the same into practical effect, I clai1n- The combination of the rail, the chair and the wedge employed to secure the rail in the chair, substantially as described; with a thin bar or strip F of iron or steel having one of its sides rounded and provided with sharp studs f projecting at intervals from this rounded side, said strip being held or partly embedded in the wedge so that the studs f are firmly engaged in the wedge, and, after the wedge and the attached strip are driven in place, the ends of said strip being bent back against the sides of the jaw of the chair, all substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 2d day of July, A. D. 1897.

FREDERICK W. SCHROEDER.
